Korrektur zu P0008675
A.Buchanan: The notation is a bit wearying. Do you think “-2.5, dann h#1” could work? (2022-06-19)
Mario Richter: Yes, I wasn't happy with the notation too, since it could lead to the wrong impression that White first makes two series-retractions followed by three series-retractionsd by Black.
I'm not 100% satisfied with the “-2.5," since IMHO it lacks the nnformation who starts the retractions ... (2022-06-19)
